(Cl. 194l02) 2 Claims.

This invention relates to .coin testing devices and has as its principal object the provision of ejecting means especially adapted for .use in the type of testing device having a coin transporting member such as a slide with a coin pocket therein and a ledge beneath the pocket supporting the coin during transport, the ledge having a drop-out opening through which coins of less than a certain diameter may pass before reaching their normal destination, the improvedejecting means including the provision of means in said pocket for causing the coin to shift to one side thereof prior to arrival opposite the dropout opening, and an ejecting finger adapted to push the coin toward the drop-out opening whereby undersized coins will be instantly pushed into the drop-out opening and thereby defeat fraudulent manipulation of the slide by pushing the same with unusual speed in an effort .to move an undersized coin so rapidly that it will not have time .to drop into the opening.

Viewed from another aspect, the principal object of the invention is the'provision of means in a coin slide for working a coin into a position relative to a drop-out opening so that ,there will be .a maximum of clearance between an undersized coin and the slide to facilitate approximately instantaneous movement of the undersized coin .into the drop-out opening, and means acting upon the coins to push the same toward said opening .for movement instantly into the latter if the coin is undersized, whereby to prevent defrauding the slide by moving the same so rapidly past the drop-out opening that the undersized coin, due .to .its own inertia, does not have time to work into the dropout opening.

Other objects, advantages and novel aspects of the invention reside in certain details of construction, as well as the arrangement of parts of the preferred embodiment described hereinafter in view of the annexed drawing, in which:

Fig. 1 is a vertical longitudinal section through the improved slide;

Fig. 2 is a horizontal section looking down along line .22 and showing the slide in top plan;

Fig. 3 is an enlarged fragmentary plan of the coin pocket and the slide;

Fig. 4 is an enlarged fragmentary perspective of the coin pocket and ejector or presser; while Fig.5 is an enlarged transverse section through the slide and mounting .in the direction of line 55 of Fig. 4.

The invention has been embodied in a type of coin tester commonly referred to as a coin slide,

for the reason that it includes -a coin transporting member in the form .of ,a .reciprocable slide in which there is a coin pocket adapted to carry a .coin within the plane of the slide for transport relative to certain testing devices and to .a final destination for acceptance .or rejection.

Such a device is shown in Fig. 1 and includes a frame structure including ,a mounting plate Ill through which extends a sleeve structure .H providing .slidingsu-pport fora reciprocable coin transporting member or slide 12. A coin pocket I3 is provided in the slide and in the normal positioning of the latter is accessible at .one side of the mounting plate Ill .to receive a coin.

The sleeve structure includes ,a drop-out opening 14 beneath the pocket l3 in coin receiving position and through which coin elements .of less than .a certain .diameter may .pass before the slide 1.2 is moved from its coin receiving position. .At the rear end of the slide 12 on the opposite side of the mounting plate :I 0 is an opening 15 which registers with a sight opening 16 above a well .ll into which the coins are ultimately transported and which may be said to constitute the destination of a .coin transported by the .slide.

An auxiliary slide 1.8 is mounted for parallel reciprocation beneath the main slide and is provided with .a coin opening t9 normally registered with the .well I] and openings I5 and 16. The bottom of the well is formed by a shelf '28 upon which coin elements may rest .in plain sight through the openings l5 .and 15 after transport by the slide.

Spring means 2| having one end attached as at .21 to .the slide .IB and the ,oppositeyend 22 attached .to the shelf 20, normally urges the auxiliary slide l8 into the initial position shown in Fig. .1 with its opening l9 registered with the well and overlying the shelf 20. When the slide [2 is moved a certain distance inwardly, a shoulder 22 (Fig. 2) about midway along a 1ongitudinal slot 23 in the main-slide is brought to bear against a pin 24 rigid .with the auxiliary slide and automatically couples the latter for movement with the main slide the .remainder of the la-tters stroke.

The arrangement is such that by the time the shoulder 22 engages the pin 24, the coin pocket I 3 in the main slide will be approaching a depressed portion 25 in the ledge beneath the slide so that the coin may drop out of the slide into the depressed portion for continued movement by lug i3a toward the well 11, and by the time the coin is ready to drop into the well, the auxiliary slide l8 will have been advanced to withdraw its opening l9 from registry with the well and cause the rear (left-hand) portion thereof to block movement of the coin onto the shelf 20 so long as the main slide I2 is fully advanced. As soon as the main slide is retracted, the auxiliary slide is moved back to normal position, and when the opening l9 thereof is again in registry with the well, the coin will be permitted to drop onto the shelf 20 where it will rest in view through the openings l and I6. Subsequent operation of the slide will cause such coin to be moved by the auxiliary slide off the shelf 20 for discharge into a receptacle (not shown).

As most coins possess certain characteristics such as diameter, thickness and diamagnetic properties in order to negotiate the transit into the well, various additional testing means such as a magnet 26 and a feeler dog 2'! are provided along the path of the coin to test the same and prevent its arrival at the well if it is not possessed of the requisite properties.

The testing means or dog 21, it may be observed, serves a dual function in that it will operate as a testing means apart from the present invention, but is also arranged and constructed to coact in an especial manner in the arrangement of the present invention. In its ordinary function as a testing means, the dog 21 is provided with a nose 2B which is urged, as a result of the action of spring means 29, to bear concentrically of the pocket against the profile of the coin as the latter moves beneath the dog. If there be no coin in the pocket the nose portion 28 projects therein to block further movement of the slide, or if the coin be of less than a requisite thickness the nose portion will again block the slide. Likewise, if the coin is apertured or disfigured in certain respects, the nose portion 28 will prevent movement of the coin therepast. On manner in which the nose portion 28 of the dog may block the slide is illustrated in Fig. 4 where the dog is shown depressed due to the absence of a coin in the pocket 13.

Adrop-out opening 30 is provided in the sleeve or frame structure beneath the dog 21 and is so dimensioned that its opposite side portions 3| and 32 constitute a ledge means upon which a proper coin element C (Fig. 5) may ride for safe transport past the opening, the diametric distance across the drop-out opening between the ledge parts 3| and 32, however, being calculated to approximate very closely the diameter of a proper coin so that coin elements C having a diameter only slightly less than that of a proper coin will not be supported by the ledge means 3| or 32 but will drop through the opening 30, which, it may be observed, constitutes the principal drop-out opening with which the invention is concerned and which is referred to in the claims.

It will be apparent that the dog 21, and particularly itsnose portion 28, bears down against all coin elements in the pocket l3 and tends .to push the coin elements into and through the drop-out opening 30. It has been possible heretofore to move the slide [2 so rapidly on its inward stroke that illegitimate coin elements and tokens having a diameter only slightly less than that of a legitimate coin, could be carried over the opening 30 before working into the same and before the dog 21 could operate to positively urge the coin into the opening.

The present invention prevents such fraudulent manipulation of the slide by providing means for working the coin, whether it be legitimate or not, into a position of maximum clearance between one side of the coin and one of the sides 3| and 32 of the drop-out opening, thereby reducing the time lag which existed heretofore between the instant the undersized coin was moved over the drop-out opening .and the time the dog or the weight of the coin could effect displacement of the coin toward or into the dropout opening, for it will be appreciated that it is only necessary that one side of the coin be worked out of the pocket toward the drop-out opening to arrest movement of the slide, and this being so, if the coin can be worked into a position to maximize the otherwise necessary clearances between the edges of the same and the margins of the drop-out opening, the time lag will correspondingly be minimized.

To this end, the coin pocket I3 (Fig. 3) has been especially shaped by positioning or offsetting one side portion 35 thereof slightly in advance of opposite side portions 36 at the rear or trailing end of the pocket relative to the direction of advance or inward movement of the slide l2.

One satisfactory method of thus offsetting a side portion of the coin pocket is by providing two centers A and B for the opposite arcuate margins or wall portions of the pocket, one of the centers B being offset a slight amount transversely of the slide and also in advance of the center .A toward the rear end of the slide. Thus, 7

the side or margin 36 of the pocket has its center at A, while the leading or offset portion 35 of the pocket has its center at B.

As a result of the foregoing construction, the coin element C resting in the pocket l3 initially as shown in the full line position of the pocket in Fig. 3, will be worked to the opposite side 36 of the pocket as the slide moves toward the drop-out opening 30, as illustrated in dotted line representation of the pocket and coin in Fig. 3. As indicated at D in the full line representation at the left of Fig. 3, it will be apparent that there is a considerable portion of the edge of the coin resting on the supporting ledge 32 but as indicated at E in the dotted line representation at the right of Fig. 3, it will appear that shifting of the coin has brought one edge of the coin thereof as close as possible to the edge of the ledge 32 without permitting the coin to drop through the opening, and in this latter position, if the coin element be only slightly smaller in diameter than the proper coin C, the clearances at the point E will be of an optimum value cal culated to be such that the aforementioned time lag necessary to permit the undersized coin to drop through the opening 30 will be appreciably reduced so that the weight of the undersized coin alone would be suflicient to cause the same to move more quickly into the drop-out opening than would be the case with the. old type of construction.

o further hasten the positive movement of the undersized coin into the drop-out opening and augment the speed of such movementresulting from the shifting of the coin into a position of maximum clearance, the dog 21 coacts with the improved pocket construction by urging its nose portion 28 against the coin as shown at the right of Fig. 3, so that the reduced time lag is further taken advantage of and it becomes virtually impossible to move an undersized coin past the opening 30 by operating the slide at any speed.

It is important to observe that shifting of the coin as indicated at the right of Fig. 3 displaces the point of contact of the nose 28 of the dog from the center line of the coin toward the clearance point E 50 that the effort of the dog is to depress the clearing edge part E of the coin in advance of the rest of the coin.

The various advantages and objects of the invention may be accomplished by modifications of the particular embodiment specifically described herein, and it is intended that the ap pended claims shall include all equivalent arrangements fairly coming within their call.

Having thus described our invention, what we claim as new and desire to protect by Letters Patent is:

1. A coin testing device having, in combination, a reciprocable coin transporting slide provided with a coin receiving pocket in which coin elements are received for transport to a certain destination from an initial position, means providing a drop-out opening between said initial position and destination and through which undersized coin elements of less than a certain diameter may pass before reaching said destination, ledge means beneath said slide for supporting a coin in said pocket during transit toward and past said drop-out opening, said pocket being of approximately circular form with opposite arcuate wall portions having different radii of curvature, the center of one radius being ofiset relative to the center of the other radius laterally of the slide and also in advance of said center toward said drop-out opening, whereby a trailing side portion of said pocket is offset to cause a coin element in the pocket to shift toward the opposite side of the pocket laterally of the slide as a result of movement of the coin by the slide toward said drop-out opening.

2. A coin testing device having, in combination, a reciprocable coin transporting slide provided with a coin receiving pocket in whichcoin elements are received for transport to a certain destination from an initial position, means providing a drop-out opening between said initial position and destination and through which undersized coin elements of less than a certain diameter may pass before reaching said destination, ledge means beneath said slide for supporting a coin in said pocket during transit toward and past said drop-out opening, said pocket being of approximately circular form with opposite arcuate wall portions having different radii of curvature, the center of one radius being ofiset relative to the center of the other radius laterally of the slide and also in advance of said center toward said drop-out opening, whereby a trailing side portion of said pocket is ofiset to cause a coin element in the pocket to shift toward the opposite side of the pocket laterally of the slide as a result of movement of the coin by the slide toward said drop-out opening, and means arranged opposite said drop-out opening to engage coin elements in said Pocket and yieldingly urge the same toward said drop-out openments into the latter.
